I can understand sports tape on feet but why on a boomerang?

We’re not quite sure where it came from, but a new photo of the Big Red Button office has surfaced. This photo shows Bob Rafei sitting next to a board with concept art for new characters and enemies that will appear in the Sonic Boom game for Wii U. The image was found by Sonic Stadium forum members Eitarou and A Real Human Bean, though where they actually found the photo isn’t clear. Be sure to click it to see it in the full resolution. Another SSMB member, Storme Prince, distorted the picture to give a clearer view of the new characters.
